ffmpeg and x265 allow you to do this too. frame-threads=1 will use 1 thread per frame addressing the issue OP mentioned, without big perf penalty, in contrary to
'pools' switch which sets the threads to be used for encoding.
Memory mapped files also known as sections in VMS/NT have just two advantages:
* Fewer context switches among user space / kernel syscalls
* No need to copy _modified_ data into the swap. The behavior for read only data doesn't change
> Fewer context switches among user space / kernel syscalls
Note that each page fault to read an mmaped page is also a context switch from user space into the kernel. The kernel entry/exit paths for syscalls and page faults have much in common.
Mmaped pages can in principle use fault-ahead to reduce the number of page faults when sequential access is detected. An equivalent reduction is available for read syscalls by reading larger blocks at a time.
In practice, mmap files are faster in some scenarios compared with read syscalls and slower in others. Same with O_DIRECT reads, those are faster in some scenarios and slower in others.
If you want the old stricter Google behavior be sure to check the "Verbatim" option under 'tools', or add "&tbs=li:1" to your uri.
Around 2008 Google started testing a new search engine logic, codenamed caffeine?, which eventually became the default. Without being sure, I think verbatim uses the old engine which wasn't trying to be smarter than you and your query, certainly is stricter and reminds the old Google a lot.
True. Aware of verbatim, though oddly forget and assume “quoted” text is verbatim. Personally I would perfect Google provide option to have verbatim on by default and enable non-verbatim per keyword; obviously average user would not like that.
EDIT: Tested if verbatim flag fixed the issue above, it did not; Google still randomly returns or does not return results, returns description with the query shown in description (or does not), etc
Oddly, if you get no results, and add [stack exchange] to query, which in theory should be from same index since it a more narrow subset of the prior, does return results, which is odd:
it's subjective of course, but I find context manager decorators very pythonic, I still remember the 'whoa! that's beautiful' moment when I 1st learned about them.
But most importantly, generators as enclosures are used everywhere today with the whole async-await paradigm.
I absolutely agree – it's the specific usage in the class that I don't like. Having a factory instead of using the constructor, with that IMHO not that obvious interaction with the context manage. A factory that is actually a context manager just seems non-trivial, and given that there is more straightforward solution available, I would avoid it.
The claim of the article that mount Everest is the tallest point from the earth's center happens because earth's surface, relative to its size, is as smooth as a billiard ball. Even the tallest mountains are nothing. So high mountains located at the equator can easily "outperform" higher mountains elsewhere.
And who is going to stop them, when even multi-million companies just shallow the pill(like GDPR) and even try to market it positively that they are gonna adopt it first.
Big business massively lobbied against the GDPR. One big reason it ended up so strict is because the final negotiations happened to coincide with the Snowden revelations, giving cover for politicians to resist the lobbying.
I'm pretty sure previous privacy laws did little to EU businesses. (Some local more restrictive ones like German neither.)
LThis one will not do anything much like you said either. There ate much mote critical laws that are being tampered with such as tax code and employment laws.
